It should be said that even though your not using certain characters, they will gain 50% of all the EXP that you earn whilst they are part of your 'team'. (i.e. All three people in the active party will gain 100% of EXP, and those that are in your backup party, will gain 50%). In the cases when certain characters aren't in your party at all, they will not gain any EXP.
Complete the game, and after the credits, you will be prompted to save. Doing so will create a 'clear data'. Loading this will start a new game, with all obtained Score Pieces, Party Level 6, Piano Music, Costumes, and the Hero's Crest. All enemies and bosses will also be stronger and tougher.
